Unlocalized items

Under the page or story "painted" theme has unlocalized items.

For example:

Code: echo t('Posted on !date by !name', array('!date' => format_date($node->created, 'medium'), '!name' => theme('username', $node)));

Give us string: Posted on Пнд, 2009-06-08 18:18 by admin

"Posted on" and "by" must be localized automatically.

In the "pushbutton" theme I found code: print $submitted
As I see $submitted is a system variable and used well in default Drupal themes.

If you change your code to print $submitted it will work fine.
